CLOTH-NAPPING MA'CHINE.

SPECIFICATION forming part of Letters Patent No. 522,560, dated July 3, 1894. Application fi ed December 2, 1392- Serial No. 453,899. (No model.)

Cloth-Napping Machines, of which the following is a specification.

This invention has relationto that class of napping or teaseling machines in which the villous or nap surface is produced uponcloth by means of card-clothed rollers running in contact with the cloth, and particularly to the kind of machines mentioned in which a plurality of napping rollers are constructed and arranged to rotate on their own axes inbear- .ings connected with a 'drum or drum-head and at the same-time to be revolved around the sa1d drum, the rollers in their movements being brought into contact with the surface of the cloth, as the latter'passes through the machine.

It is the object of the invention to provide means whereby the guide rollers for the cloth may be adjusted with the greatest readiness and with the utmost nioety with respect to the napping rolls so as to cause the latter to act upon the cloth with greater or less vigor and efficacy, as circumstances may suggest.

It is also the object of the invention to pro: vide means whereby the cloth under treatment may be frictionally drawn through the machine and maintained in taut condition at all points at which it is acted upon. 7

It is also the object of the invention to pro vide means whereby the movement of the cloth through the machine may be stopped instantly without arresting or affecting the operatlon of other portions of the machine than those which accomplish the movement of the cloth.

It is also the object-of the invention to pro- I vide means simple in construction and arl rangement for the efficient operation of the a left-hand end view ofthe same.

machine as a whole, alias I will now to describe and claim. 7

Reference is to be had to the annexed drawproceed ings, and to the letters and figures marked thereon, forming a part of this specification,

the same letters and figures designating the same parts or features, wherever they occur.

. Of the said drawings-Figure 1 is what may be termed a right-hand, end view of the machine embodying the invention. Fig. 2 is Fig. 2 is a sectional detail view showing the manner of frictionally connecting the roll-driving gears with theirshafts. Fig. 3 is a sectional right-hand end viewtaken on a line running centrally through the machine. Fig. 4 is a top plan view of a portion of the right-hand end of the machine. Fig. 5 is a sectional end View showing the immediate means for operating the napping rolls, and illustrating the course of the'cloth through the machine where it is acted upon by the napping rolls, the parts being drawn to a larger scale than in Figs. 1,

'2 and 3. Fig. 6 is a longitudinal sectional showing the manner of adjusting the guide rolls for the cloth with respect to the naplaying roll, and for adjusting the clearing roll with reference to the nap-laying roll. Fig. 8 is a sectional view taken on the line 8 8, (Fig. 7,) looking toward the left. Figs. 9 and 10 are detail views hereinafter more particularly referred to. Fig.11 is asectional detail view showing a modified form of means for operating the napping rolls. Figs. 12 and 13 show another modified form of means for operating the napping rolls.

In the drawings a designates the frame of the machine which may be of the form represented or of any other suited to thepurpose. c is the main shaft from which all of the moving parts of the machine are operated.

d (see Fig. 6) is a cylinder or drum head connected with the main shaft, provided on its periphery with bearings e for the j0ur= nals of the napping rollers f, the said journals, on the right-hand end of the machine being provided with pinions g which are em gaged by the teeth of a gear wheel 72, turning loose on the shaft 0. The said gear wheel h is provided with a sleeve 4, upon which is secured a gear wheelj engaged by a gear 76 on an independent shaft Z; and compounded with the gear is a gear m which is engaged and driven by a gear a secured to the main shaft 0.

The main shaft, cylinder, and gear 1?. will be driven in the direction of the arrow shown in proximity to the main shaft in Fig. 2, and as the gear atis larger than the gear m, the napping rollers f will be rotated upon their axes in the same direction through the gears h and m and their intermediaries. This system of gearing is shown only for the purpose of illustrating a kind of means that may be employed for operating the machine, but said means per se forms no part of my presentin- Vention.

It will be understood, of course, that the napping rollers are covered with card clothing of a nature to adapt them to raise or teasel a nap upon the surface of the cloth with which they come in contact.

The cloth, in its course through the machine passes up over a guide roller 1, down under a guide roller 2, inward around a guide roller 3, up over a cloth-covered frictionally driven roll 4, down under a guide roller 5, up against a guide roller 6, up around a guide roller 7, back around a cloth-covered frictionally driven roll 8, inward under a guide roller 9, upward around a guide roller 10, up and down around a cloth-covered frictionally driven roll 11, down under a guide roller 12, downward and rearward under a guide roller 13, rearward and forward around a cloth-covered frictionallydriven roll 14, inward around a guide roller 15, downward against a guide roller 16, down under a guide roller 17, up around guide rollers 18 and 19, down under a guide roller 20, up over a guide roller 21, inward and outward around a cloth-covered frictionally driven roll 22, outward around a guide roller 23, up over a frictionallydriven roll 24, and forward over suitable guide rollers to the point of starting.

The frictionally driven rolls 4, 8, 11,14, 22, and 24 serve to draw the cloth through the machine, and may be of increased diameter successively from the first to the last-mentioned so as to keep the cloth under treatment properly stretched or under the desired tension where it is acted upon by the napping rolls.

The frictionally driven rolls8 and 14 which are arranged on opposite sides of the cylinder, have their bearings connected with the arch 0, which is divided centrally, and hinged at its divided point as at p to the frame a. The journals of the guide rollers 7, 9 co-opcrating with the roll 8, and the guide rollers 13, 15 co-operating with the roll 14, are also arranged in bearings supported by the arch 0. The lower ends of the arches o are arranged to rest upon cams q secured upon shafts r, journaled in the frame, on the ends of which shafts are cranks s in the lower or nuts 6 through which the screw-threaded por-' tions of a rod a pass, said rod it being arranged so as that it may be turned in 1ts bearings but not to move longitudinally. The rod a may also be provided with abandwheel '1; or other means whereby it may be turned, and so operate the shafts r, cams q and arches 0 to adjust the rolls 8 and 14 and their co-operating guide rollers nearer to or farther from the cylinder, and consequently nearer to or farther from the napping rollers.

It will be seen, particularly upon an 1n- 'spection of Fig. 3 ofthe drawings that the cloth will be acted upon by the napping rollers at four points, namely, between the guide rollers 6 and 7, 9 and 10, 12 and 13", and 15 and 16, and that by adjusting the arches through the medium of the screw rod a, which adjustment may be readily accomplished and made with the utmost nicety and while the machine is in motion if need be, the cloth may be brought nearer to or removed farther from the napping rolls so that the latter may be made to operate with greater or less vigor or force in raising the nap.

Another matter of great consequence in the feature of the machine just described-is that all of the adjustments are effected in unison and are of absolutely the same degree or extent.

Each of the rolls 4, 8, 11, 14 and 22 is driven by a gear 20 which is engaged by a pinion 0c compounded with a pulley 1], a belt passing around all the said pulleys and a pulley son the main shaft c, each pinion a: and its pulley 3 being journaled on a stud secured to the frame. Each gear 10 is arranged to turn loosely on the shaft of its roll, but is frictionally conspliued on said shaft and bearing against a friction disk I) which rests against the face of the gear w, (see Fig. 2.) A nut a provided with a hand-wheel cl is turned upon the screw-threaded end of each roll, and bears against a friction collar 6 or other similar means, the latter bearing against the hub of the friction disk b, which means serve to regulate the force with which the gear wheel 20 is frictionally bound to its shaft, and as a consequence regulates the force with which the drawing rolls 4, 8, 11, 14 and 22 act upon latter is put.

f is a tightening pulley secured to one end of a lever g pivoted upon the frame of the machine, around which pulley the belt which drives the pulleys y passes, so that by supporting the handle end of the lever g upon a pin h, as shown in Fig. 2, the belt may be tightened and thedrawing rolls operated, as

. before described, and by throwing the said ,lever off the said pin the belt will be reni dered so slack as to fail to operate the draw ing rolls, without affecting the other parts of the machine.

nected with its shaft by means of a disk a outer ends of which are pivoted or swiveled the cloth and the tension under which the.

h designates the nap finishing or laying roll which operates upon its opposite sides on the cloth, as is best shown in Fig. 3. It will be seen that the guide rollers 17 and 20, below the nap-finishing roll are journaled in swinging arms or levers '5', in the upper ends ofwhicli are pivoted nuts 3' engaged by the screw-threaded portion of a rod Z, provided with a groove m intermediate of its threaded points, in which groove fits a feather or rib itconnected with the frame, so that when the rod 1' is turned, as it may be by a handwheel 0' on its ends it may bring the upper ends of the levers t" closer together or move them farther apart, andso bring the guide rollers 17, 20 nearer to or move them farther from the nap finishing roll to make the latter operate with greater or less energy on the nap.

. 1a is a clearing roll for the napping rolls f, and q is a clearing roll for the nap-finishing roll it, which clearing-rolls are mounted in adjustable bearings, as shown in Figs. 3 and 8 so as to cause them to act properly on the nap rolls.

' lhe nap-finishing and clearing rolls are driven by suitable belting as shown, or may be operated in any other suitable Way. In Fig. 11 there is shown a rope system, so called, for operating the cylinder from the main shaft, and this system may be employed instead of the gearing before described.

In the last-mentioned figure r designates a graduated groove pulley secured upon the sleeve z of the gear h ands is a groovedpulley secured upon the main shaft outside of the pulley r. t is a bracket secured to the frame in the lower end of which bracket is journaled a groove pulley u. t) is a frame arranged to slide vertically on ways connected with the frame 25', in which sliding frame is journaled a grooved pulley w. A weight w is attached to the sliding frame so as to draw the same downward and tighten the endless rope y, which passes around in one of the grooves of the pulley 7', down aroundthe pulley u, up over the pulley s',down around the pulley w and back again to the pulley r. By this simple means it-will be seen that the gear 72. which operates the pinions on the napping rolls f may be efficiently driven from the main shaft.

In Fig. 12, there is shown a slightly modified form of rope-driving mechanism. In this case the rope y passes from the graduated grooved pulley 0" down around a pulley a loose and longitudinally movable upon a shaft 6 supported in a frame 0 secured to the floor. From the pulley a the rope passes up over a pulley d on a stud connected with the frame; thence down around a pulley e supported in bearings in a frame f similar to frame 0 thence the rope may pass around pulleys 9 k around the pulley 8, down around a pulley t in the frame 0 and thence up around the pulley r. Both the pulleys e and i may be loose upon their shafts so as to move longitudinally thereon, and both may be supported in a weightedvertically-movable frame as is the case with the pulley w, shown in Fig. 11. Again, the pulley 'w, e and 1' maybe supported in a swiveled bracket 3' as shown in Fig.13.

Other modifications, it is obvious, may be made in the form and arrangements of parts comprising the invention Without departing from the nature or spirit thereof.
